The relationship of the Camberwell Family Interview (CFI) with two self-report scales purported to measure levels of expressed emotion was assessed. Fifteen schizophrenic patients and 22 of their relatives completed the Level of Expressed Emotion Scale (LEE) and the Influential Relationships Questionnaire (IRQ). The relatives of patients also participated in Camberwell Family Interviews (CFI). Results supported the value of the self-report measures in evaluating the affective environment of patients with schizophrenia.
